NUMBERING HEAD FOR PRINTING-PRESSES.

SPECIFICATION forming part ofLetters Patent No. 374,708, dated December 13, 1887.

Application filed November 4, 1886. Serial No.217,981. (No model.)

To all whom it may concern.-

Be it known that I, JOHN G. SAUER, of the city, county, and State of New York, haveinvented anew and Improved Nu mbering-Head for Printing-Presses, of which the following is a full, clear, and exact description.

My nvention relates to a numbering -head for printing-presses constructed with a main casing and inner frame carrying the numberng-disks, and arranged to receive an out-and- 1n movement in the main casing from contact with the'platen of the press,which movement is utilized to turn the numbering-disks for consecutively numbering the sheets as they are printed.

The invention consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference isto be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of a part of a printing-press, showing my new numberinghcad set up with the type. Fig. 2 is a plan View of the numbering-head with one of the side plates removed, parts being shown in section to show the construction. Fig. 3 is a sectional elevation taken 011 the line a; x of Fig. 2. Fig. 4 is a perspective View of the inner frame removed from the main casing. Fig. 5 1s a perspective View of the front pawl-yoke for turning the numbering-disks. Fig. 6 is a perspective View of the numbering-disks removed from the inner frame. Fig. 7 is a transverse sectional elevation on the line y y of Fig. 2; and Fig. Sis an end view of the inner frame, showing the ratchet wheel and pawl in the position they are held by the end piece of the main out-er frame, no part of the latter being shown except the pivots of the ratchet and pawl shown in section. Fig. 9 is an enlarged elevation of the numbering-head, the back plate being broken away to clearly show the click it and pin Z.

A represents the main casing,composed of the end pieces, a a, back plate, a", (which unites the inner frame, B, which carries the numbering-disks d d, back pawls, c c, and pawl-yoke 0, provided with the front pawl-plate, f, pivoted in the yoke and held forward by the spring f and provided, also, wit-h several pawls f, for turning the numbering-disks d successively, as hereinafter described.

The inner frame, B, which carries the disks d and pawl-yoke 0 upon the shaft g,on which they turn easily, is placed in the main casing A,and is normally held, forced somewhat out thereform by the action of the two springs h, so that when pressure comes upon the disks d in printing the inner frame will be forced into the main casing a short distance against the pressure of the springs h. This inward movement is utilized for turning the yoke G forward upon the shaft 9 for causing the pawls f, acting in conj unction with the ratchets 9, formed upon the side of the numbering-disks, to turn said disks to bring the typed surfaces thereof successively into position for printing. The movement of the pawl-yoke G is effected through the medium of the leverj, pivoted to the outside of the inner frame, B, and provided with a stud, j, that reaches through a slot, j and enters the slotj, made in one of the check-piecesf of the yoke C, so that the swinging of the leverj will communicate a like motion of the yoke O and the pawlsf carried thereby. The yoke O and lever j are normally pressed to" the position shown in Figs. 7 and 8 by the action of the'light spring 2' pressing upon the edge of one of the checkpieces of the yoke. The yoke and lever j will occupy this position at the time the platen of the press strikes the disks din printing,and the contact of the platen with the disks (Z will prevent them from turning upon the shaft 9, and at this time the platen will press the whole inner frame, 13, within the outer main frame, A. This inward movement ceases when the outer surfaces of the disks (1 reach typehigh position, and during this movement the leverj strikes the stud e,forn1ed upon the small ratchet-wheel e, and turns said wheel against the tension of the coiled spring 6 which is set in a recess, 6 formed in the inner surface of the end piece, a, of the main frame A. The ratchet wheel 6 is set in said recess e over the spring o and said wheel is made fast to a short shaft, 6, journaled in the end piece, a, and the inner end of the spring 5 is attached to this shaft, while its outer end is made fast to the inner surface of the recess 6, so that the turning of the ratchet-wheel e, by the inward movement of the lever j, as above stated, puts a tension upon the said spring 0 and this tension is retained by the check It, attached to the inner surface of the end piece, a, of the main casing A. The inner corner of the inner frame, B, is provided with a pin, Z,which reaches over the tail-piece of the click k, as shown in Fig. 8, sothat when the platen of the printing-press is moved out of contact with the disks d, and the frame B thus left free to be moved outward by the springs 71,the said pin will trip the click k, thus leaving the ratchet-wheel 6 free to be turned in the direction of the arrow in Fig. 8, which will cause stud e to moveleverj downward or outward, which in turn will swing the yoke O outward and cause the pawls f thereof to turn the disks d one space, ready for the next inipression. This action is repeated with each reciprocation of the inner frame, B.

To prevent the disks 4 from being turned too far and from turning back, I provide the inner frame, B, with the above mentioned back pawls,c, pivoted upon the rod 0, which pawls are pressed against the ratchets g, as shown in Fig. 7, by the plate-springs 0 one for each paw]. These pawls c, pressing, as they do, against the long angle of the ratchet-teeth of the wheels, also serve to stop the disks (1 in their revolution exactly in the proper position, so that the type thereof will squarely strike the paper and produce a good impression.

The series of pawls f are of gradually-diminishing length, as shown in Fig. 5, and in each of the ratchet-wheels g is formed a notch, 9 into which the point of the pawls drop after a complete revolution of the disks, so that at the outset the longest pawlf will turn the end disk (the others remaining at rest) until the said longest pawl'reaches the recess gt. The point of the pawl will then drop into this recess and thus bring the next shorter pawl into action, which will continue until the recess in its ratehetwheel is reached, whereupon the next pawl in like manner will come into action, and so on through the whole set of pawls.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The main casing A, provided at one end with a spring, 6, and ratchet 6, having pin 0, in combination with the click 7c,attached to the main casing, the inner casing, B, the leverj, and the pin Z, for tripping the click, substantially as described.

2. The main casing A, provided at one end with a spring, a and ratchet 0, having pin 6, in combination with the reciprocating inner easin g or frame, B, provided with the numbering-disks, the pawl-yoke O, the click 7.", and leverj, substantially as and for the purposes set forth.

3. The main casing A, provided with the coiled spring 6 ratchetwheel 6, pin a, and click 7c, in combination with the inner casing, B, provided with the lever and pawl-yoke 0, all arranged to operate substantially as and for the purposes described.

4. The inner frame, B, provided with the numbering-disks d, pawl-yoke C, and leverj, for operating the numbering-disks,and placed in the main frame provided with springs h, in combination with a studded ratchet-wheel located in the main casing and acted upon by a spring and check, the inner frame being provided with a pin, Z, for tripping the check, substantially as and for the purposes set forth.
